HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 588,022, dated August 10, 1897.

Application filed August 13, 1896. Serial No. 602,659. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE SINGLETON, a citizen of the United States, and a resident of Dover, in the county of Morrisand State of New Jersey, have invented certain new and useful Improvements in Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the invention which will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings; which form a part of this specification.

My invention relates to horseshoes and detachable toe and heel calks therefor; and its object is to provide an improved construction whereby the calks may be readily removed and replaced when desired without removing the shoe or the nails which secure it to the hoof.

The invention consists in the combination, with a horseshoe having downwardly-depending lugs on the under side formed with dovetailed grooves extending from one end to near the other end and with alined opposite slot-s near the open end, of a calk having a dovetailed rib on its upper side engaging with said groove and a key passing through said slots and abutting against the end of the rib, as hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a central longitudinal section of a horseshoe constructed in accordance with myinvention. Fig. 2 is a bottom view of the shoe, the calks being removed. Fig. 3 is'a perspective view of one of the heel-calks detached. Fig. 4 is a detail cross-sectional view of one of the ends of the shoe.

In the said drawings the numeral 1 designates the shoe, provided on the under side with the usual crease or channel 2 and formed with nail-holes 3.

At each end and at the toe the shoe is formed on the under side with a downwardly-depending lug 4. These lugs are similar in all essential respects and are formed with dovetailed grooves 5, extending from one end to near the opposite end, forming, as it were, opposite dovetailed flanges connected together at one end. Near the upper ends the lugs are formed with opposite alined slots or recesses 6 to receive a key hereinafter described.

The numeral 7 designates the calks, which may be sharpened or not, as desired, each formed on its upper sides with a dovetailed rib 8, corresponding with the groove in the lugs and somewhat shorter than the calks themselves. The numeral 9 designates a key adapted to engage with said slots in the lugs.

In practice the calks are connected with the lugs by sliding the ribs into the grooves, the front ends of the ribs abutting against the closed ends of the lugs. The keys are then driven into or through the slots and bearing .against the outer ends of the ribs Will securely hold the calks in place and prevent accidental detachment or loosening of the same from the shoe.

To remove the calks, the keys are driven out, when the calks can be forced out of the grooves by a blow from a hammer or other tool. It will thus be seen that the calks do not in any manner interfere with the nails which hold the shoe to the hoof, so that they can be removed and re placed Without removing the shoe or any of the nails which hold it in place.

Having thus fully described myinvention, what I claim is The combination with a horseshoe having lugs on the under side provided with dovetailed grooves forming tapering flanges connected together at the contracted end forming a solid portion, and said flanges disconnected at the expanded or large ends forming a passage-Way for the ribs of the calks, and the flanges near said open end provided with opposite slots, of the calks having dovetailed ribs on their upper or inner sides engaging with said grooves and one end abutting against the solid connected ends of said flanges, and the keys driven through said slots and bearing against the opposite ends of said ribs, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto aflixed my signature in presence of two witnesses.

GEORGE SINGLETON.
